Description

Assembling device

The present invention relates to an assembly device, mainly referring to an assembly device that can be easily assembled and disengaged.

Conventional assembling methods include various types such as screwing, nailing, bonding, welding, and the like. The composition is in a fixed form after being combined by means of nailing, bonding, and welding, and is not easy to separate and lose the composition. The screw connection method mainly has a screw and a nut, and the composition can be set with a perforated screw and then screwed with the nut to fix it, so that after the combination, the screw can be disengaged by reverse rotation, which can be disassembled conveniently. However, when the position of the composition is not easy to set the nut (such as the central position of the hollow frame), it is difficult to make the screw engage the nut missing.

Another example is the expansion screw of No. TWI289632 with a nail seat and a bolt. The nail seat is a hollow tubular body, with a nail cap on the upper part, and an action area with several long holes and several turning and segmented strips in the middle part. one end. The end has a screw hole, so that the nail seat can be inserted inwardly through the perforation of the wall, and its nail cap is nailed to the outside of the wall to fix it. Also make the bolt penetrate the nail seat and thread the screw hole in the lower part of the nail seat, and stretch the outer end of the bolt toward the outside so that the long strip at the working end can be turned and fixed against the inner side of the wall, and the nail seat can be positioned on the wall. And the bolt protruding from the outside of the wall can be used for hanging.

However, after the structure is combined, the nail base is integrated with the wall and is difficult to take out, and cannot be reused, and the bolt can be reversed and separated from the nail base, which may fall off and lack integrity.
